Gas detector

A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. This type of equipment is used to detect a gas leak and interface with a control system so a process can be automatically shut down. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.

Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion. This type of device is used widely in industry and can be found in locations, such as on oil rigs, to monitor manufacture processes and emerging technologies such as photovoltaic. They may be used in firefighting.

Gas leak detection is the process of identifying potentially hazardous gas leaks by sensors. These sensors usually employ an audible alarm to alert people when a dangerous gas has been detected. Common sensors include infrared point sensors, ultrasonic sensors, electrochemical gas sensors, and semiconductor sensors. More recently, infrared imaging sensors have come into use. All of these sensors are used for a wide range of applications and can be found in industrial plants, refineries, waste-water treatment facilities, vehicles, and homes.

Use (law)

Use, as a term in real property of common law countries, amounts to a recognition of the duty of a person, to whom property has been conveyed for certain purposes, to carry out those purposes.

Uses were equitable or beneficial interests in land. In early law a man could not dispose of his estate by will nor could religious houses acquire it. As a method of evading the common law, the practice arose of making feoffments to the use of, or upon trust for, persons other than those to whom the seisin or legal possession was delivered, to which the equitable jurisdiction of the chancellor gave effect. To remedy the abuses which it was said were occasioned by this evasion of the law the Statute of Uses of 1536 was passed. However it failed to accomplish its purpose. Out of this failure of the Statute of Uses arose the modern law of trusts (see that article for further details).

Development of the use

One reason for the creation of uses was a desire to avoid the strictness of the rules of the common law, which considered seisin to be all-important and therefore refused to allow a legal interest to be created to spring up in the future. Although the common law recognised a use in chattels from an early period, it was clear by the end of the fourteenth century that land law had no room for this notion. Uses, nonetheless, satisfied contemporary needs in fifteenth century England. Its first application in relation to land was to protect the ownership of the land by the Franciscan Monks, who were pledged to vows of poverty and unable to own land. This enabled the feoffee to uses for the benefit of a cestui que use. The common law did not recognise the cestui que use but affirmed the right of ownership by feoffee to use. The term "use" translates into "Trust" and this was the legal beginning of Trusts and the use of trusts to defeat feudal, death and tax dues.

Gas

Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture would contain a variety of pure gases much like the air. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colorless gas invisible to the human observer. The interaction of gas particles in the presence of electric and gravitational fields are considered negligible as indicated by the constant velocity vectors in the image. One type of commonly known gas is steam.

The gaseous state of matter is found between the liquid and plasma states, the latter of which provides the upper temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention. High-density atomic gases super cooled to incredibly low temperatures are classified by their statistical behavior as either a Bose gas or a Fermi gas. For a comprehensive listing of these exotic states of matter see list of states of matter.

Gas (musician)

Gas is a music project of Wolfgang Voigt (born 1961), a Cologne, Germany-based electronic musician. Voigt cites his youthful LSD experiences in the Königsforst, a German forest situated near his hometown of Köln, as the inspiration behind his work under the name Gas. He has claimed that the intention of the project is to "bring the forest to the disco, or vice-versa".

Aliases and projects

Voigt is known for his numerous, nearly inexhaustible list of one-off projects and aliases. Of these, his best known is arguably Gas, a project that saw the marriage of ambient music and 4/4 techno.

Other names under which Voigt has released music include, but are not limited to, All, Auftrieb, Brom, C.K. Decker, Centrifugal Force, Crocker, Dextro NRG, Dieter Gorny, Digital, Dom, Doppel, Filter, Freiland, Fuchsbau, Gelb, Grungerman, Kafkatrax, Love Inc., M:I:5, Mike Ink, Mint, Panthel, Popacid, Riss, RX7, Split Inc., Strass, Studio 1, Tal, Vinyl Countdown, W.V., Wassermann, and X-Lvis.

Characteristics

Gas (1981 film)

(not to be confused with a similar sounding 1970 film Gas-s-s-s)

Gas is a 1981 Canadian comedy film released by Paramount Pictures, the plot of which was inspired by the 1979 energy crisis.

Plot summary

A small Midwestern town is thrown into chaos when the local oil tycoon (Sterling Hayden) orchestrates a phony oil shortage in order to increase profits. A news reporter (Susan Anspach) tries to uncover the plot, and a radio DJ in a helicopter (Donald Sutherland) reports on the craziness caused by the gasoline shortage.
